BMW 850 CI Fuelling Problem
Discussion
Hey there
I've just acquired a 1994 BMW 850CI which has been standing still for over 5 years.
At this point I am only interested in getting it to run, it has good compression and sparks fine but no fuel getting through.
Does anyone have any suggestions of whether there are any known issues with fuel pumps "sticking" over time or dodgy relays?

Stick your VIN number in here and select the fuel system, it'll give you an exploded view of the parts

Can you hear the pump running?I've just acquired a 1994 BMW 850CI which has been standing still for over 5 years.

Have you checked for pressure at the rail? - normally a schreader type valve on the fuel rail (under the plastic engine cover)
Injectors themselves can stick over time when not used - sometimes a few little light taps on the metal bodies of the injector can "bring them back to life" if it's done at the same time as trying to start then engine
If the fuel filter is anything like the E38/E39 one - it's huge, expensive to replace as it's viewed by BMUU as "lifetime"
